In this study, PRP after FUE increased hair density and length in men with androgenetic alopecia, with no scalp redness reported beyond the first month.

This review highlights that alopecia areata is characterized by three immune endotypes, and while JAK inhibitors offer temporary control, upcoming multi-omics diagnostics and immune reprogramming strategies may achieve longer-lasting remission, according to this analysis.

This study found that the liposomal Sesbania grandiflora formulation significantly improved hair and scalp health in adults with hair loss compared to placebo over 180 days, enhancing factors such as hair density, thickness, growth rate, and tensile strength, with no related adverse events reported.

This study found that Indulekha Bringha scalp serum significantly reduced hair shedding and improved hair density more effectively than 3% Redensyl serum in healthy Indian adults experiencing hair loss.

Alopecia Areata may involve reduced antioxidant defenses in hair follicles, affecting stem cell function.

In this study on C3H/HeJ-engrafted mice, a single injection of BMD-1141 significantly increased anagen hair follicle counts and enhanced hair regrowth compared to daily high-dose ruxolitinib, suggesting it stimulates hair growth by influencing the hair cycle rather than altering immune response.

In this study, injectable microdepots containing rapamycin and poly(lactic-co-glycolic acid) were developed and demonstrated to effectively promote hair regrowth in mice by sustaining drug release and inducing anagen phase transition in hair follicles through modulating autophagy and the Wnt/β-catenin pathway.

This study examined proteomic changes in Inner Mongolia cashmere goat skin, finding 631 proteins differentially regulated during hair growth stages; key keratin proteins, crucial for hair follicle development, were localized in secondary hair follicles.

In this study on mice, a hydro-alcoholic solution containing kopexil significantly enhanced hair growth and increased hair-promoting factors without causing notable liver or kidney toxicity compared to minoxidil.

Ganoderma lucidum extract may help treat stress-related hair loss.

This study found that salvianolic acid B significantly enhanced hair growth and delayed hair follicle cycle progression in mice and human hair models, suggesting potential as a treatment for hair loss.

Teak leaf extract hair tonic was tested for hair growth and safety.

This study developed a mathematical model to explore the interactions between hair cycle dynamics and immune system activity in alopecia areata, providing insights into disease progression and potential targets for treatment by simulating immune response effects on hair follicles.

Hair follicle stem cells and mitochondria are key for hair growth, and targeting their activity could lead to new hair loss treatments.

In this study using C3H/HeJ mice, a single subcutaneous injection of the fusion protein PTH-CBD increased anagen hair follicle counts and promoted hair regrowth comparably to daily oral ruxolitinib, potentially by enhancing beta-catenin production and stimulating anagen transition.

This study identified specific lncRNAs and mRNAs differentially expressed in miniaturized follicles compared to normal follicles in patients with androgenetic alopecia, with AL136131.3 potentially inhibiting hair growth and accelerating follicle transition to catagen through effects on glycolysis-related genes.

In a study on hair loss treatment, researchers found that a serum containing Cinchona succirubra extract and caffeine improved hair density and reduced hair loss in individuals with acute telogen effluvium after 16 weeks of use, with significant improvements observable after just 4 weeks.

In this study, a single subcutaneous dose of PTH-CBD showed similar hair regrowth to daily oral ruxolitinib in mice with alopecia, possibly through increased beta-catenin and anagen transition stimulation.

This study suggests that targeting the activation of transit-amplifying cell-derived progenitor cells may help prevent hair loss from chemotherapy and radiotherapy by promoting hair follicle regeneration.

Some TikTok hair loss remedies like rosemary oil, onion juice, and garlic gel show promise, but more research is needed and they might delay proper treatment.

This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.

This study found that a shampoo containing a 6-active ingredient complex increased β-Catenin production in human hair follicle dermal papilla cells to levels comparable to Finasteride, suggesting potential for promoting hair growth. It also showed good cleaning efficacy, volume, and shine in a sensorial study.

This study found that shikimic acid significantly promoted hair growth in a mouse model and enhanced hair shaft elongation in human hair organ culture, suggesting its potential as a treatment for alopecia.

This study established a model using nude mice to successfully graft human scalp skin, maintaining hair follicle growth and skin integrity for at least two months, which may aid preclinical research.

This study identified several age-related changes in gene expression associated with the extracellular matrix of scalp dermal fibroblasts, which may impact hair follicle maintenance in women over 40.

This study observed that a 3D culture model of hair follicle cells showed an anagen-like phase between days 3 to 6 and transitioned to a catagen-like phase by day 7, highlighting cell differentiation and structural development over time.

This study suggests that FGF18 may enhance radioresistance in telogen hair follicles by inducing cell cycle arrest, potentially serving as a radioprotector against radiation-induced hair follicle damage.

In this ex vivo study, inhibiting Ezh2 with a small molecule slowed human hair growth by decreasing proliferation and increasing apoptosis in the outer root sheath.

This study found that photodynamic therapy may offer a new option for removing nonpigmented hair, although it was less effective than diode laser for black hair in mice.

This review discusses various drugs and chemicals potentially causing hair loss, mechanisms involved, and suggests models for testing but reports no new clinical findings.
